Application Challenges
In the EVTOL sector, maximising flight time is paramount. The TerraE 40P cell addresses this challenge by providing high energy density and robust discharge capabilities. The ability to optimise cell selection, duty cycle, and flight speed directly impacts the operational efficiency of UAVs. With the increasing demand for long endurance drone batteries, the 40P's specifications allow for extended missions without compromising safety or performance. The challenge lies in ensuring that the battery can deliver the required power while maintaining thermal stability, especially in extreme environments. The TerraE 40P's design mitigates risks associated with overheating and ensures reliable performance across various mission profiles, making it a vital component for UAV operators looking to enhance mission endurance.
Why this Cell
The TerraE 40P cell is specifically designed to meet the rigorous demands of EVTOL applications. With a maximum continuous discharge rate of 45 A, it is positioned in the top-quartile compared to the database median of 30 A, allowing for high discharge rates essential for rapid acceleration and climb. Its volumetric energy density of 566 Wh/l is among the highest, providing the necessary energy for extended flight times. This cell's gravimetric energy density of 215 Wh/kg ensures that UAVs remain lightweight, which is crucial for maintaining optimal flight efficiency. By selecting the TerraE 40P, UAV manufacturers can achieve a balance between weight and performance, ultimately leading to improved mission outcomes and reduced operational costs.
How Model-Based Design Helps
Simulation and model-based design play a critical role in optimising the selection of the TerraE 40P cell for UAV applications. By modelling load profiles and thermal behaviour, engineers can predict how the cell will perform under various conditions, including different duty cycles and environmental factors. This approach allows for accurate assessments of voltage sag, heat generation, and usable energy throughout the flight envelope. For instance, simulations can identify the optimal charge and discharge rates, ensuring that the cell operates within safe thermal limits while delivering the required power. This predictive capability not only enhances the reliability of the UAV but also reduces the risk of mid-air failures, making it an invaluable tool for designers aiming to maximise flight time and efficiency.
